Hours 00-11 become AM (with 00 rewritten as 12 AM), and hours 12-23 become PM (with 12 staying 12 PM and 13-23 subtracting 12). Minutes and seconds never change – only the hour is transformed.

00:00 is 12:00 AM – midnight. In 24-hour notation the day starts at hour zero; 12-hour notation labels that same moment as 12 AM.

13:00 is 1:00 PM. Any 24-hour time from 13:00 through 23:00 subtracts 12 from the hour and labels it PM.
